In all the darkest pages of the malign supernatural there is no more terrible tradition than that of the Vampire, a pariah even among demons. Foul are his ravages; gruesome and seemingly barbaric are the ancient and approved methods by which folk must rid themselves of this hideous pest. Even to-day in certain quarters of the world, in remoter districts of Europe itself, Transylvania, Slavonia, the isles and mountains of Greece, thepeasant will take the law into his own bands and utterly destroy the carrion who--as it is yet firmly believed--at night will issue from his unhallowed grave to spread the infection of vampirism throughout the countryside. Assyria knew the vampire long ago, and he lurked amid the primaeval forests of Mexico before Cortes came. He is feared by the Chinese, by the Indian, and the Malay alike; whilst Arabian story tells us again and again of the ghouls who haunt ill-omened sepulchres and lonely cross-ways to attack and devour the unhappy traveller.
